Term

Definition

Btl

Bus-Target-LUN: Identification for a parallel SCSI device

CHAP

Challenge-Handshake Authentication Protocol: If CHAP is enabled, the target

 

requires the initiator to negotiate CHAP authentication using the CHAP secrets

 

(passwords). An initiator may reject this negotiation

DP

GbE port used for data movement and inband management

data port

 

firmware

Software stored in read-only memory (ROM) or programmable ROM (PROM);

 

firmware is often responsible for the behavior of a system when it is first

 

switched on

GbE

A protocol for transferring block-level IO over telnet networks; speed at which

Gigabit Ethernet

data is passed over Ethernet

IETF

Internet Engineering Task Force: The standards body responsible for Internet

 

standards such as SNMP and telnet through a community of network designers,

 

operators, vendors and researchers concerned with the evolution and smooth

 

operation of the Internet

initiator device

A component which originates a command

iSCSI

Internet SCSI (Small Computer System Interface), a protocol to link data storage

 

facilities over the Internet or an intranet developed by the Internet Engineering

 

Task Force (IETF); carries SCSI commands over IP networks to facilitate data

 

transfers over intranets and manage storage over long distances

LED

Light-emitting diode, a type of diode that emits light when current passes through

 

it; visible LEDs are used as indicator lights on all sorts of electronic devices

LUN

Logical Unit Number: a SCSI identifier of a device

MPn

GbE port used for management but which may also be used as a data port

Management Port

 

Metadata

Information (file marks, directory name information) stored on the tape to assist

 

data management; content of the metadata is the sole responsibility of the

 

NDMP Data Management Application

NAS

Network Attached Storage: storage elements connected to a network to provide

 

file access services to computer systems; an NAS Storage Element includes an

 

engine to implement the file services and one or more devices to store data;

 

NAS elements may be attached to any type of network; an NAS host system

 

uses a file system device driver to access data and NAS systems interpret these

 

commands to execute the necessary internal file and device I/O operations

NDMP

Network Data Management Protocol: A protocol for data backup and restore

 

over telnet networks which uses file-based IO

SCSI

Small Computer Systems Interface: a processor-independent standard for

 

system-level interface between a computer and intelligent devices including hard

 

disks, floppy disks, CD-ROM, printers, scanners, etc.
